javascript - soundcloud api - 如何检查录制的轨道是否处于事件状态？

Question

如何检查录制的轨道是否已上传并处于嵌入状态。

我想在上传完成后显示轨道的嵌入预览。

但是我在解析 url 时从 scPlayer api 收到 404 错误。

可以跟踪轨道的可用性，基于我可以使用 sCplayer()

用于解析轨道。

有什么帮助吗？

谢谢 彼得

我知道在 /tracks 资源中有一个名为 state 的属性，它可能就是您要查找的内容。

在他们的文档中，他们给出的示例值是finished，因此在轨道准备好之前它可能会读取uploading 或processing。注意:我自己还没有尝试过。

或者，可能有另一个值，如 duration 或 stream_url，在轨道准备好之前将读取 NULL。
